yes, all correct answers 
the main screen alarm flashes when lightning is detected, and you can even have a lightning.wav sounds played (e.g thunder, LOL)
see my graph:
http://www.weather-display.com/windy/gb/lighteninggraph.gif
which in wd shows the counts at the graph position
this same screen in WD also can show the nextstorm info (tick to enable that in the general /misc setup), and yes that can be used alongside the 1 wire counter

Whew - glad about that. I felt like a doctor flying solo with his first patient :lol:
Thank you very much for answering. A person could save around $300 in making their own.
I’ll give it a whirl next month. Having the Lightnining dector interfaced with WD looks nice and Brian’s suggestion of having a Thunder wav play as a warning is neat also.
Hey Brian… That new Weather Shop at that Shopping Center looks cool !! I don’t believe there is anything in the U.S. like that. It’s very nice looking !!
Hi
I’ve made the lightning detector:
But the led (receiver) lights always, and never go off, what should i do?
Kevin
#1 are you sure the wiring is correct, especially are the diodes wired correctly?
#2 disconnect the antenna, what happens?
#3 if the led doesn’t turn off in #2 connect the base of Q1 to ground and see if that turns it off.
can you post the component values?
But the led (receiver) lights always, and never go off,
By this do you mean the opto coupler in the next stage.
This design looks to be the original “Tim Bitson” one from here http://homepage.mac.com/tbitson/weather/owlm/index.html
in which case following this stage is an opto coupler and then a 1-wire interface. Is that what you are trying to do?
Hey,
I think i found the problem, i’ve been the connection between Q2c en D2 forgotten
Can this be the problem?
Kevin
Uhm, ground wire to earth ground? where is that? i have not that cable
connection between Q2c en D2 forgotten
I’m not sure that D2 is a critical component. Its not there on later designs.
ground wire to earth ground? where is that
Look at the diagram you posted - its the green wire marked ‘ground’. It needs to go to an earth stake or a water pipe with a good earth connection.
Ok i have solderd the last connexion and the led dont burn now, even if i make a spark with a electrick lighter…
I dont know what to do now, i have make earth on my radiator.
Kevin
Do you happen to own a cheap voltmeter? If so, it should be pretty easy to make some measurements and figure out what is going on.
If i turns the led: plus on min and min on plus, the led burns, so he has power, i have checked the circuit 2 times full and its good with no mistakes…
The sellers on the electro shop here tells my that it has no senses how you put the resistors on the board and the other parts are exactly as the picture,
Kevin
If i turns the led: plus on min and min on plus, the led burns
Where in the circuit do you have the LED mounted?
At the end of the coax cable…
What are you using for an antenna?
A copper pipe 22mm
Ed1,
The interface to the PC is via a DS9097U or any other acceptable one wire computer interface. The DS9097U is the cheapest of the interfaces and connects to the com port. When strikes are detected WD displays the counts the Lightning Data screen. Shown here:
Ok I have been following this very closely as I really would like to add some sort of Lightning detection to my station…
Assuming (cause it’s true) there is no way i can (will) afford a Boltec or other commercial application.
I would need the following as a minumum (I think) (totally clueless on this one wire stuff)
One of the following from: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2983
DS9097U-009
DS9097U-E25EPROM Compatible Adapter
DS9097U-S09
(Which one?)
and:
http://www.hobby-boards.com/1wireboards/ld3-r2_lightning_detector.html (Assembled)
Would I need anything in addition to connect to the Computer? Or do i just need to add some sort of “Antenna”?
Thanks for any assistance,
Bob

the i link is better than the standard adaptor, but a bit more pricy
of those others,
http://www.aagelectronica.com/aag/en-us/dept_2.html
should be the one
antenna:
12cm of wire is all that needed
and so the circuit board needs to be next to that
i have my whole thing just inside my office window, and it picks up lightning (needs to be closer, otherwise you can get a 50km radius)
Ok now I am confused LOL
I assume you mean that the
The Link (1-Wire Adapter)
THE LINK
Advanced DB-9 Serial to 1-Wire™ Bus Interface
from this page: http://www.aagelectronica.com/aag/en-us/dept_1.html is better than the adapters I listed?
Also what about the:
DS9490R USB 1-Wire Adapter
From the same page as above?
Can this be used in place of the other adaptors or is this to convert one of the above adaptors to USB use?
Yikes I am getting a headache LOL
